I started on 4 strings...then got a 5 around this time last year. I rearranged a few songs for 5 string, incorporating the lower notes. But after getting my bass from Nino(4 string J/MM Geddy inspired bass), I haven't played any of my other basses and have rearranged the songs back to 4 string. I almost feel like I should use the 5 for some songs since I have it and it's a nice bass(Schecter Model T-5), but it's been cased since getting the "El Nino". Is this wrong? Anyone else "accidentally" abandon 5 strings for 4?
